The toolkit helps businesses in the north-west reduce their use of resources and cut waste production.
Based in Greater Manchester, the scheme boasts almost 1,000 participating businesses. It said that those in the scheme save about £12 million a year from a total capital investment of only £5.5 million, as well as reducing CO2 emissions by 18,000 tonnes a year.
The programme works with each business, conducting audits, bringing in special advisers, providing a telephone helpline and finding ways to help them save energy, water and materials by examining all their manufacturing processes, and making their buildings more energy-efficient.
Northwest Regional Development Agency chief executive Steven Broomhead praised the scheme: "During the past five years, Enworks has succeeded in positioning the north west at the vanguard of environmental business excellence and it is only natural that the programme is now a model for the rest of Europe to follow."
